/* These are bit masks and shift counts to use to access the various

   fields of an instruction.  To retrieve the X field of an

   instruction, use the expression

        (i >> OP_SH_X) & OP_MASK_X

   To set the same field (to j), use

        i = (i &~ (OP_MASK_X << OP_SH_X)) | (j << OP_SH_X)

   Make sure you use fields that are appropriate for the instruction,

   of course.

   The 'i' format uses OP, RS, RT and IMMEDIATE.

   The 'j' format uses OP and TARGET.

   The 'r' format uses OP, RS, RT, RD, SHAMT and FUNCT.

   The 'b' format uses OP, RS, RT and DELTA.

   The floating point 'i' format uses OP, RS, RT and IMMEDIATE.

   The floating point 'r' format uses OP, FMT, FT, FS, FD and FUNCT.

   A breakpoint instruction uses OP, CODE and SPEC (10 bits of the

   breakpoint instruction are not defined; Kane says the breakpoint

   code field in BREAK is 20 bits; yet MIPS assemblers and debuggers

   only use ten bits).  An optional two-operand form of break/sdbbp

   allows the lower ten bits to be set too, and MIPS32 and later

   architectures allow 20 bits to be set with a signal operand

   (using CODE20).

   The syscall instruction uses CODE20.

   The general coprocessor instructions use COPZ.  */
